Bulletin of Insectology 61 (1): 179, 2008 ISSN 1721-8861 Anatomical investigations of the male reproductive system of selected species of Macrosiphini Karina WIECZOREK Department of Zoology, Faculty of Biology and Environmental Protection, University of Silesia, Katowice, Poland Abstract Histological sections and whole mount preparations of five species of Macrosiphini [Impatientinum asiaticum Nevsky, Hypero- myzus (Hyperomyzus) pallidus Hille Ris Lambers, Myzus (Myzus) cerasi (F.), Rhopalomyzus (Judenkoa) loniceare (Siebold) and Uroleucon obscurum (Koch)] were examined. Key words: Hemiptera, Aphidoidea, Aphididae, Macrosiphini, male reproductive system.
